sleepless for no good reason

It's 3:15 a.m. and I'm awake. I'm awake and I'm updating birthday reminders with my new email. How pathetic and sorry is that? How completely traumatic is it that I'm awake at 3:15 in the morning? Even worse, I'm tired. My eyes are heavy & gritty but I can't get comfortable and I damn sure can't get back to sleep. And not a drop of liquor in sight...
